CVE-2026-20220
Full vulnerability record from the local CVENow database.
Description
A vulnerability in the web-based management interface of Cisco Crosswork Network Controller could allow an authenticated, remote attacker to execute arbitrary commands on an affected device. This vulnerability is due to insufficient input validation in the configuration template engine of the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system in limited areas of the file system. This vulnerability affects only areas of the operating system for which the template user has write permissions. To exploit this vulnerability, the attacker must have valid template user credentials with write permissions. Template users with read permissions cannot exploit this vulnerability.

"value": "Una vulnerabilidad en la interfaz de gestión basada en web de Cisco Crosswork Network Controller podría permitir a un atacante remoto y autenticado ejecutar comandos arbitrarios en un dispositivo afectado.\n\nEsta vulnerabilidad se debe a una validación de entrada insuficiente en el motor de plantillas de configuración de la interfaz de gestión basada en web. Un atacante podría explotar esta vulnerabilidad enviando una solicitud manipulada al dispositivo afectado. Un exploit exitoso podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo subyacente en áreas limitadas del sistema de archivos. Esta vulnerabilidad afecta solo a las áreas del sistema operativo para las que el usuario de plantilla tiene permisos de escritura.\nPara explotar esta vulnerabilidad, el atacante debe tener credenciales válidas de usuario de plantilla con permisos de escritura. Los usuarios de plantilla con permisos de lectura no pueden explotar esta vulnerabilidad."
